Nuclear fission was first theorized on the 19th of December 1938, by the German chemist Otto Hahn and Austrian-Swedish physicist Lise Meitner. It was then explained the year after, by Meitner along with Otto Frisch. Frisch named the process after biological fission, which is when an entity splits into two separate parts that resemble its original. In nuclear fission a heavy radioactive atom, such as Uranium 235(U), splits because it is bombarded by a neutron, and this releases energy, along with some neutrons. A chain reaction occurs so these neutrons hit other Uranium nuclei with the fission process then releasing even more energy and neutrons. Fission can be controlled or uncontrolled. Controlled fission is visible today in nuclear power plants, while an example of uncontrolled fission are nuclear weapons, which were unfortunately used against Japan in the second world war (Hiroshima, 6 August 1945 - Nagasaki, 9 August 1945).

hi Lucas,
a great perspective on a proven and effective approach. Your research is insightful and should be considered in how we deal with energy for next 50 years. Well done 👍

Hi Lucas, thank you very much for your work you are doing. We live in a very ignorant society on atomic energy issues, we have all been conditioned by the terror that has been infused into us by those who have no interest in developing atomic energy. I think it is very important to make objective information that allows people to make conscious choices that benefit the whole of society. keep it up. thank you.
So exciting to see all your research come together! I was sceptical at first but think nuclear fusion energy sounds interesting!
Impressive!Clear and objective contents!Really a great work!
